Application November 24, 1948, Serial No. 61,883

This invention relates to an air conditioning device for vehicles.

An object of this invention is to provide an air conditioning means adapted to be mounted within a vehicle so that the interior of the vehicle may be cooled.

Another object of this invention is to provide a device of this kind which includes means for evaporating water to obtain the desired cooling of air which is passed through a rotating evapo rator operated lfrom a suitable operator, such as a hand crank, or other suitable power means. This device may be connected to the air duct of a heater so that the fan associated with the heater will provide the necessary draft of air, or the air intake of the device may be directed forwardly so that the forward movement of the device will provide the necessary air force.

A further object of this invention is to provide an improved evaporating element in the form of a perforate drum having disposed therein a per- Vious cylinder formed of iibrous material, such as wood or other vegetable bers, or metal fibers, or compounds thereof.

With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawing and specification, and then more par= ticularly pointed out in the appended claim.

In the drawing,

Figure l is a perspective view of an air conditioning device constructed according to an embodiment of this invention,

Figure 2 is a sectional view taken on the line 2-2 of Figure 3,

Figure 3 is a sectional view taken on the line 3--3 of Figure 2.

Referring to the drawing, the numeral IG designates generally a housing of substantially rectangular shape, which is' formed of a bottom wall I I, opposite side walls I2 and I3, and opposite end Walls I4 and I5. A anged closure or top member I6 is removably mounted on the top of the housing IIB. A drum generally designated as I is rotatably mounted within the housing I8 and comprises end plates I8 and I9 which are secured to a tubular shaft '20.

The shaft 2B at one end extends through the 1 Claim. (Cl. 261--92) end plate or head IG and is rotatably mounted 24 carried by the end I8 and extends through a bearing 25 secured to the end Wall I4. The shaft 23 is adapted to be extended to any desired portion of a vehicle such as the dashboard, and a crank may be mounted on the outer end of the shaft 23 so that this shaft may be manually rotated if desired, or this shaft may be connected to a suitable driving means connected with the vehicle engine.

The drum I'I includes a cylindrical screen 26 which is fixed between the end members I8 and I9 and a iibrous cylinder 27 is disposed within the cylindrical screen 2%. An L-shaped nipple or pipe 28 is secured to the wall I2, extending laterally from this wall and the upper end of the pipe or nipple 28 has a cap 29 removably mounted thereon. Water is adapted to be discharged into the housing Iii through the filling nipple 28 and the housing IU is adapted to be filled to substantially the water line 30 indicated in Figure 2.

The wall I2 on the inner side thereof is provided with a longitudinally extending and hori- Zontally disposed baiiie 3 Ia, and the wall I3 is also provided on the inner side thereof with a horizontally disposed baiiie 3I. These baffles 3Ia and 3| are adapted to prevent undue surging or splashing of the water within the housing Illas the vehicle moves along the road. A discharge valve 32 is secured to the bottom wall II so that the water may be drained from the housing I0.

The end wall I4 has extending therefrom an air outlet pipe 33 which may be extended to any desired portion in the interior of the vehicle. It will be understood the intake of shaft 2i] will be extended forwardly so that air will be forced into shaft 2G as the vehicle moves along and outlet 33 may either enter the vehicle at 'any place or may be connected to a heater to give additional air at standing or slow speeds.

In the use and operation of this device, the housing I0 which may be of any suitable size may be disposed at any desired position within the vehicle such as beneath one of the seats or beneath the dash. Water is initially placed in the housing I0 to the level 33 and as the vehicle moves over the road, the drum I'I is slowly rotated so that the air entering the forward or intake end of the tubular shaft 26 will pass through the openings 22 into the interior of the drum I'I and will then pass through the moistened ber drum or cylinder 2 picking up the moisture and then passing out of the housing I through the outlet 33. The fibrous cylinder 21 may be formed of any suitable bers such as vegetable or metal bers and is suiiiciently pervious so that air may freely pass therethrough.

I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claim.

What I claim is:

An air conditioning apparatus comprising a housing adapted to receive ;a predetermined quantity :of Water, a tube openat one end to provide an air inlet and having a plurality of longitudinally and circumferentially spaced air outlet openings therein, journalled for rotation in the Wardly extending peripheral ange on :each -send Y of said screen positioned beneath the reverted -edge .ofthe adjacent .end plate for securing the V,screen thereto, .a `fibrous Water pervious .cylinder contained within said screen and spaced from said tube, downwardly inclined horizontal baies on the opposite side Walls of said receptacle each extending to a point closely adjacent said screen, and an air outlet in said receptacle, the level of the water in said receptacle normally being substantially tangential to `the lowermost peripheral point of said tube.
